Definitions
- the invention relates to a method for producing a foil of synthetic material composed of a first synthetic compound and a second synthetic compound, in which the first synthetic compound consists of a polymer and the second synthetic compound consists of a plastomer.
- the invention also relates to a synthetic fibre and to an artificial lawn suitable for sports fields, consisting of a substrate to which synthetic fibres according to the invention are fixed.
- a synthetic material having the composition according to the above introduction is generally known, in the form of a foil it is widely used as a packaging material or a roofing material. Synthetic materials are currently being used for all kinds of purposes, and significant developments in particular as regards the use of all kinds of synthetic materials in artificial lawns for sports fields have been realised the past few years.
- the splitting behaviour of the synthetic fibre can furthermore be significantly improved by stretching the fibre after the extrusion process.
- the selection of materials after the stretching process gives the fibre its strength in transverse direction, as a result of which it will split less easily.
- the artificial lawn will require much less maintenance and will thus remain playable longer. Furthermore, the risk of injury of the players is considerably reduced.
- the fibre may consist of at least one monofilament, in which case the fibre may be twined into a strand of several monofilaments.
- the fibre may according to the invention be formed as a band, and more in particular as a fibrillated band fibre.
- a fibre having a very advantageous non-splitting behaviour can be obtained in that the proportion of the plastomer in the fibre is 30-80 wt. %, and more in particular 35-50 wt. %.
- the first polymer may be polypropylene or polyethylene, and in particular (linear) low-density polyethylene, high-density polyethylene, homo-polymer polypropylene or copolymer polypropylene.
- FIGS. 1 a and 1 b are graphs showing specific mechanical properties transverse direction of a known fibre and a fibre according to the invention being subjected to a load in transverse direction;
- FIGS. 2 a and 2 b schematically show a few embodiments of an artificial grass sports field provided with a synthetic fibre obtained by means of the method according to the invention.
- the present artificial grass fibre must meet a number of requirements, inter alia as regards the rolling behaviour of the ball or other attribute of play, also in order to prevent all kinds of injuries of the players. In particular burns and grazes caused by slidings or falls should be prevented as much as possible, so that new artificial grass fibres for artificial grass sports fields are being developed in particular in order to prevent these situations.
- the current artificial grass fibres are made from a synthetic material from the group of polymers.
- the splitting behaviour of the synthetic fibres can be influenced by using a mixture or blend of polymers. It has been established by experiment that in certain situations, when a synthetic material composed of a first synthetic compound and a second synthetic compound, in which the first synthetic compound consists of a polymer and the second synthetic compound consists of a plastomer, is extruded into a fibre, the fibre that is obtained has advantageous mechanical properties, and in particular an advantageous splitting behaviour, which make the fibre quite suitable for use in artificial grass sports fields.
- the mechanical properties of the synthetic fibre thus obtained are to a significant degree determined by the molecular structure of the two synthetic compounds in the mixture.
- the two synthetic compounds are mixed and the mixture is extruded into an elongated fibre, a number of different effects on the level of the molecular structure may occur in the final product.
- a fibre which is very suitable for use in an artificial grass sports field is obtained by selecting, in accordance with the invention, a polyethylene or polypropylene for one of the two synthetic compounds and a plastomer for the other synthetic compound and extruding said blend into a synthetic fibre.
- a suitable selection of the composition or the proportion between the first synthetic compound and the second synthetic compound will result in a synthetic fibre having mechanical properties such that, due to its specific molecular structure, the fibre will inter alia split much less easily in its longitudinal direction.
- the first synthetic compound is polypropylene or polyethylene. It has become apparent that (linear) low-density polyethylene or high-density polyethylene are also suitable for use as the first synthetic compound. It is also possible to use homo-polymer polypropylene or copolymer polypropylene as the first synthetic compound.
- the plastomers (second synthetic compound) used in the synthetic fibre according to the invention that are mentioned herein are thermoplastic homopolymers of ethene and copoloymers of ethene, with one or more ⁇ -olefins having 3-10 C-atoms, in particular propene, isobutene, 1-butene, 1-hexene, 4-methyl-1-pentene and 1-octene as the comonomer, which are to be prepared by means of metallocene catalysts and other single-site catalysts.
- the proportion of comonomer ranges between 0 and 50 wt. %, preferably between 5 and 35 wt. %.
- the density usually ranges between 860 and 970 kg/m 3 .
- the plastomers are different from the polyethenes, which have been prepared by means of Ziegler-Natta catalysts, for example, in that they have a narrow molecular weight distribution Mw/Mn, with values which usually range between 1.5 and 3, and a limited degree of long chain branching. As a rule, the number of long chains amounts to maximally 3 per 1000 C-atoms.
- Suitable plastomers are produced on a commercial scale, for example by Exxon and DEX-Plastomers under the brand name Exact®, and by Dow, inter alia under the brand names Engage®, Affinity®, Exceed®.
- a suitable fibre according to the invention can be obtained by selecting a suitable mixing ratio between the two synthetic compounds, in which the weight percentage of the plastomer is 30-80%.
- FIGS. 1 a and 1 b show graphs in which the mechanical properties of an unknown synthetic fibre and the fibre obtained by means of the method according to the invention are marked off against each other.
- FIG. 1 a shows the splitting properties of the two fibres obtained by loading the fibres in transverse direction and thus determining the tear strength in MPa. The figure clearly shows that the fibre according to the invention has a higher tear resistance and will split less easily, therefore.
- FIG. 1 b shows the maximum stretch of the two fibres at the moment of rupture of the two fibres upon being loaded in transverse direction. The figure clearly shows that the fibre according to the invention not only splits less easily (FIG. 1 a ), but in addition is much stronger (FIG. 1 b ) and consequently can be used very well in an artificial grass sports fields.
- the fibre according to the invention exhibits a stretch factor of 100% (as shown in FIG. 1 b ) before rupturing upon being loaded in transverse direction.
- Tests have shown that when a suitable mixing proportion of the first synthetic compound (the polymer) and the second synthetic compound (the plastomer) is used, the synthetic fibre according to the invention that is thus obtained will exhibit a stretch factor of up to 700% before rupturing upon being loaded in transverse direction.
- FIGS. 2 a and 2 b show a few embodiments of an artificial grass sports field, in which a synthetic fibre according to the invention can be used.
- the artificial grass sports field comprises a substrate 1 , to which several synthetic fibres 2 obtained by using the method according to the invention have been fixed at the location indicated by numeral 3 , for example by tufting.
- the synthetic fibre 2 may have been extruded in the form of a band and be fixed to the substrate separately or as a bundle of fibres 2 a - 2 b which have been twined together, for example. More in particular, the fibre that has been extruded in the form of a band may be a fibrillated band fibre.
- the synthetic fibre according to the invention may be a monofilament. Also in this embodiment, several monofilaments may be combined into a bundle by twining, after which each bundle is fixed to the substrate 1 .
- the substrate has an open structure consisting of a grid of supporting yarns 1 a - 1 b , to which the synthetic fibres 2 are fixed.
